Other mistake: When Sue Ellen gets the roses from Gus, the tickets in the card have a date of April 6th 1990. This is suppose to be the summer of 1990, which means the tickets are no good. (01:03:00)
Other mistake: In the tanker truck/pick-up truck chase, after the tanker rams the pick-up and destroys the wooden shelter in the bed, you can see the Terminator turn the steering wheel right but the truck turns left instead. You have to look very closely to see this.
Other mistake: There is a patch on the jacket Harley (Rourke) wears, that appears and disappears throughout the movie. It's on the front lower right side. It is there when he's standing outside their friends' bar with Marlboro, it's gone when they are inside.
Other mistake: When Eve runs into the BMW from behind, the guy slams into his steering wheel. When you are hit from behind, you will slam backwards into your seat. It happens twice, the third time the airbag deploys and stays inflated (real airbags deflate in a second, they are not balloons).
Other mistake: In scene where Celeste follows her niece Lori to Jeffrey's Apt, she is trying to fool the Doorman and says "He's in 11-A, right?" He replies "2D." Later, when Jeffrey catches Celeste on the fir escape and let's her out via his front door, the apt door is marked "2A."
Other mistake: When Franc (Martin Short) is looking at the house to see the changes for the wedding and they are talking about the menu, Kimberly Williams starts with her hair in a ponytail, then for a split second her hair is half up in a barrette and then it's back to a pony tail (or vice versa).
Other mistake: Throughout the movie, Nick Nolte and Barbra Streisand take cab rides. There are thousands of cabbies in NYC, so how come they always get in a cab with the same license plate?
Other mistake: When Sulu tells Kirk he is coming to help, he states the Excelsior is currently in the Alpha Quadrant. The problem is the the Alpha Quadrant in the Star Trek universe is one quarter of the total Milky Way Galaxy. While technically correct, Sulu giving his position as in the Alpha Quadrant is useless to Kirk in terms of knowing when to expect help. It doesn't matter where Khitomer is in the galaxy. Sulu saying he is in the Alpha Quadrant gives Kirk absolutely no idea of when he will arrive. He could be anywhere from 5 minutes away to 5 weeks away or even further. Remember, it was originally projected to take Voyager 70 years to go from the Delta Quadrant back to the Federation in the Alpha Quadrant.
Suggested correction: The implication is that Excelsior has only very recently crossed the border from the Beta Quadrant to the Alpha Quadrant.
Even if that "implication" were true (and there's nothing dialogue-wise to indicate such) it's still useless to Kirk as to when the expect help. The dividing line between the Alpha and Beta is fully half the width of the galaxy.
Sulu doesn't expect Kirk to deduce where the Excelsior is, he tells him directly that they're unlikely to make it in time, and the reason is that they are "now in Alpha Quadrant" i.e. they were previously not in the Alpha Quadrant, i.e. they're far enough away that recently they were in a whole other quadrant of the galaxy. (I agree it's an awkward line, but it makes sense if you think of it like "I'm now in the U.S." if it's known you already live there - it means you've just returned).
Other mistake: Just before the evil robots capture Bill and Ted's girlfriends, after they crash through the window, the girlfriends ask the robots: "Who are you?" and Bill goes "Well, I'm really Evil Ted!" and unzips himself and out pops Evil Ted, and the other robot goes, "And I'm really Evil Bill!" and out pops Evil Bill. When the robots are herding the girlfriends out just before knocking them out with their breath, you can see two sets of clothes in the bottom left corner if you watch closely.
Other mistake: When the firefighter is fighting with the arsonist, the gas line is disconnected from the fireplace. Just before the dramatic explosion, the gas line ignites. This is incorrect because the fire would have started from the outlet to the gas (from ignition source to fuel source).
Other mistake: When Gomez begins to flip through his desk calendar, we see that "today" is Thursday, March 28, 1991. He then turns to the date of the "next quarter". The left hand page shows Thursday, August 8, but the right hand page shows Tuesday, September 9. (00:11:15)
Other mistake: When Daniel is at the Italian restaurant with Julia, the waiter says he will bring Daniel 9 pies. When Daniel is carrying them into the hotel after dinner, it is clear is only carrying 8 pies.
Other mistake: In the dance scene, when Mrs. Potts says "true as it can be", in one frame her eyes turn black and then turn blue again. (01:00:25)
Other mistake: In the fight scene where Bohdi helps special agent Utah you see that his surf board gets broken in two and then after the fight he is seen leaving without the board, but in the scene where he and Tyler are woken up early to go surf right before Tyler says "you look like you just saw a ghost" you see him carrying the same board.
Other mistake: There is a scene where Joe is shown taking a bullet for then-President Carter. We then see Darian visiting Joe in the hospital after the shooting, holding a picture that she drew for him. Darian looks to be about 6 or 7 years old, yet this film takes place in 1991, Carter left office in 1981, and she is supposed to be 13 in the movie. If she was 6 or 7 when Carter was in office, she would be 16/17 by 1991. (01:02:55)
Other mistake: When Joe Huff goes to the fight pit and jumps in, he has on fingerless gloves. However, during the fight he is barehanded and when the shot returns to Joe Huff he has the gloves on again.
Other mistake: After Clarice is finished interviewing Frederica Bimmel's friend, they cut to the abandoned house in Calumet City IL. The front yard is full of leaves, but yet there is only 1 lone (pine) tree in the yard, and the homes on either side do not have visible trees either.
Other mistake: In the 7th game of the season, a scoreboard shows the score with about 3:08 to go in the game as 43-12, but next the announcer says they lost 35 to 12.
Other mistake: In the ending credits, Gary Carter is listed twice.
Other mistake: Early in the film, before they were signed to a record deal the Doors were playing small clubs around L.A. in 1966. After one of these gigs, a promoter comes up and asks Jim Morrison how old he is, in which he replies "21." Morrison was born in 1943, so the youngest he could have been is 22, not 21.
